To all whom it may concern:

Be it known that I, FRANK H. GA'rnER ooAL, a citizen of the UnitedStates, residing at Wilmette, in the county of Cook and State ofIllinois, have invented new and useful Improvements in DisappearingSashes for Porch Constructions, of which the following is a full, clear,concise, and exact de scription, reference being had to the accompanyingdrawing, forming a part of this specification.

My invention has for its object the production of a device in which aperfect clo sure against the elements is provided.

A further object is the production of a device in which the sash may berigidly locked in closed position.

A further object is the production of a simple and eflicient device thatcan be easily attached to constructions and one not liable to get out oforder.

These and such other objects as may hereinafter appear are attained bymy device, an embodiment of which is illustrated in the accompanyingdrawing, in which Figure 1 represents a sectional View of a porchconstruction showing my device in position.

Fig. 2 represents a perspective view of the spring locking member.

Like numerals of reference indicate like parts in the several figures ofthe drawing.

Referring now to the drawing which shows a porch sash equipped with mydevice inclosed position, A represents the outside casing, B the jamb, Cthe parting stop, D the stop, F the lower bar and G the upper bar of thesash, H the outside sill, I the inside sill, J the glass of the window,K the pocket within which the window can be dropped, and L thecorresponding pocket in the upper portion within which the window can beraised in order to permit the movement of my improved closure M. Anordinary mortise lift G, is set in the inner face of the lower bar F.

The closure M is provided with a hinge N hingingly mounted on the innersill I at O. The closure is provided with a downwardly extending lip orbead P and an upwardly extending lip or bead Q. The hinge N, in additionto the leaves R-S which are screwed to the sill and side of the memberM, has a supplemental tightening lever T with an extended arm or handleU and an upwardly extending gripping arm V termiating in a curved catchW. As shown in Fig. 1 the sash is closed and the catch W enters themortise lift G and its end engages a groove 5 in the mortise in thelower bar. When the window is open the members i V and U occupy theposition shown in Fig; 2. The two members are then turned upwardly onthe pivot S until the catch engages the mortise lift in the lower barand the lever U is swung down swinging the member T back into theposition shown in Fig. 1 and locking the sash tightly against theclosure M.

In order to release the sash, it is simply necessary to swing the memberU upwardly again and then the catch V is released and the parts swungback toward the inner sill I. The closure M may then be swung upwardlyon the pivot O and the window sash dropped into the pocket K after whichthe closure will be swung back entirely covering the pocket K andfitting closely over a raised lip or bead Z on the outside sill.

By this construction it is possible for me to have the porch tightlyinclosed by rea son of the lip P engaging the bead Z and the lip Q;engaging a corresponding cutaway portion in the inner surface of thelower sash F, making it impossible for any water or snow or wind toforce its way between the sash and the sill.

While I have shown a method of closing this completely by my improvedspring member, it is evident that other means may be employed withoutdeparting from the spirit of my invention.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

1. The combination with a sash of a pocket positioned below said sashand adapted to receive the same, an inner sill, a covering memberhingedly mounted on said inner sill and adapted to cover said pocket, alocking member mounted on the inside of said covering member and adaptedto be brought into engagement with the sash to force the same downtightly against said covering member.

2. The combination with a sash of a pocket positioned below said sashand adapted to receive the same, a beaded front sill, an inner sill, acovering member hingedly mounted on said inner sill provided With adownwardly projecting flange on its tightly against said member andcause the lower outer end and an upwardly projectlower flange on saidmember to engage the ing flange on its upper inner end, and adapthead onthe sill and the sash to engage the 10 ed to cover said'poeke'n' alocking member upper flange.

5 mounted on the inside ofsaid covering mem- In Witness whereof I havehereunto subher and adapted to be brought into engagescribed my name.ment with the sash to force the same down FRANK H. GATHERCOAL.

Copies of this patent maybe obtained for five cents each, by addressingthe "Commissioner of Patents.
